During the January 17-18 power outage, both SLAC and Stanford University sent emergency notices and updates via telephone and text messages. Hundreds of SLACers who signed up with the SLAC911/ALertSU system received these messages not only on their SLAC phone lines, but also personal phones and e-mail accounts of choice.

SLAC community members can sign up any time, through the SLAC Phone Directory. Just search for yourself, then press the Edit button on the dark blue line that says Optional Information (SLAC/Non-SLAC). Opt in to the system by choosing up to three phone numbers and/or one email address and tagging them as "SLAC911" using the View drop-down menu. Information added here will be added to the AlertSU system.
